Abstract

La présente invention concerne un tube amortisseur (100). Le tube amortisseur (100) comprend une ou plusieurs sous-unités (110), une micro-couche gainante (112) et une pluralité de fils gonflables dans l'eau (114). La ou les sous-unités (110) contiennent une pluralité de rubans de fibres optiques (106). Chaque ruban de fibres optiques de la pluralité de rubans de fibres optiques (106) comprend 12 fibres optiques. En outre, chaque fibre d'une pluralité de fibres optiques (108) est une fibre optique colorée. De plus, la micro-couche gainante (112) entoure la ou les sous-unités (110). En outre, la ou les sous-unités (110) ont une couche de revêtement de matériau sans halogène à faible émission de fumée.
